This research utilised a ‘stimulated recall’ methodology [Calderhead, J. 1981. “Stimulated Recall: A Method for Research on Teaching.” British Journal of Educational Psychology 51: 211–217] to explore the potential of African folklore, specifically Ghanaian folk stories in the development of children’s reflective thinking about social life. The research was based on Ghanaian folklore for children, which is popularly known as ‘By the Fireside Stories’, encapsulated traditionally as Anansesem or Spider stories among the Akan of Ghana. Data were collected through storytelling to a group of children and inviting them to recall their concurrent thinking during and after the storytelling. The children’s cognitive recall processes were stimulated by questions and story character dramatisation recorded on a digital video recorder and played back to the children. Findings showed major contributions to children’s learning and development related to imagination, concept formation and thinking, and beyond the self in social relationship. This paper draws attention to how traditional oral storytelling can be an important part of early childhood education to develop children’s reflective thinking about social life.  相似文献

The objective of this study was to develop and validate an instrument to assess the attitude of student pharmacists toward prayer in general and in particular as it relates to their academic performance. To fulfill the study objective, faculty from seven colleges of pharmacy located at Christian universities collaboratively developed the Student Prayer Attitude Scale (SPAS). The items were used to assess the attitudes of student pharmacists toward prayer as well as the effects of prayer on personal lives and academic performance. Faculty investigators asked 1,563 students to complete the survey and received 677 valid responses. A principal components analysis with promax rotation was conducted and revealed a two-factor structure: (a) general attitude toward prayer and (b) specific attitude regarding the impact of prayer on academic performance. Analysis of variance was used to compare student responses by religious identity. Students identifying as atheist or agnostic were significantly different in their responses than students from theistic religions; however, the responses of students from various theistic religions were not significantly different from one another. Faculty concluded that SPAS is a reliable tool for measuring student attitudes toward prayer. The use of such a tool could help faculty tailor educational opportunities to allow pharmacy students to explore prayer more fully and be aware of its impact on the patients they serve.  相似文献

The aim was to study the genotoxic effect of high concentration of thyroxine (T4) in vivo in peripheral blood lymphocytes (PBL) of the patients suffering from thyroid disorders. The effect was compared by performing in vitro experiments with addition of increasing concentration of T4 (0.125–1 µM) in whole blood samples from healthy donors. Cytokinesis-blocked micronuclei (CBMN) assay method was used to assess the DNA damage in the PBL. The study included 104 patients which were grouped as control (n = 49), hyperthyroid (n = 31) and hypothyroid (n = 24). A significant increase in micronuclei (MN) frequency was observed in hyperthyroid patients when compared with the hypothyroid and euthyroid group thereby suggesting increased genotoxicity in hyperthyroidism (p < 0.001). A significant increase in MN frequency was observed at T4 concentration of 0.5 µM and above when compared to lower T4 concentrations (0.125 and 0.25 µM) and basal in in vitro experiments (p = 0.000). The results indicate that the T4 in normal concentration does not exhibit the genotoxic effect, as observed in both the in vivo and in vitro experiments. The toxicity of T4 increases at and above 0.5 μM concentration in vitro. Therefore acute T4 overdose should be handled promptly and effectively so as to avoid the possible genotoxic effect of high concentration of T4 in vivo.  相似文献

The US Natality files provide information on medical procedures and health related behavior during pregnancy and childbirth. The data set represents nearly the universe of mothers who give birth in the US, providing the most complete coverage possible of medical care and health behavior among a specific patient population. We document gaps in outcomes by education of the mother and the changes in these educational gaps during 1989-2002.  相似文献

This paper empirically evaluates Caplow and McGee??s (The academic marketplace, 1958) model of academia as a prestige value system (PVS) by testing several hypotheses about the relationship between prestige of faculty appointment and job satisfaction. Using logistic regression models to predict satisfaction with several job domains in a sample of more than 1,000 recent social science PhD graduates who hold tenure-track or tenured faculty positions, we find that the relationship between prestige of faculty appointment and job satisfaction is modified by PhD program prestige. Graduates of high prestige PhD programs value prestige more highly and graduates of low prestige programs value salary more highly. We explain our findings by incorporating reference group theory and a theory of taste formation into our model of the academic PVS, which identifies PhD programs as sites of socialization to different tastes for prestige (a process of cultural transmission) in addition to their well recognized role in transmission of human and social capital. We discuss practical and theoretical implications of our findings in relation to efforts to measure PhD program quality and to understand the structure of academic labor markets.  相似文献

The purpose of this study was to explore the nature of requisite teacher knowledge for teaching lower-track science students. Using video accounts, student focus groups, and teacher reflections researchers documented missteps, dead-ends, and unfruitful trajectories informed by the teacher’s incoming knowledge and compared these instances to necessary modifications informed by students’ voices and cultural artifacts. Our study revealed the shifting nature of sociocultural and pedagogical content knowledge of the teacher immersed in a context unlike that he experienced as a student. Results showed that teachers of majority backgrounds could learn to teach diverse students with at least moderate success from the perspective of their students. Implications for research and teacher education in diverse settings are discussed.  相似文献

The migration from print books to ebooks is more than a change of format; it is also the first step in an ongoing process, whose final outcome is hard to predict. Ebooks are likely to lead to a restructuring of the industry by enabling cross-border commerce. This in turn is likely to lead to difficult disputes over territorial rights. It appears probable that these disputes will be resolved by an assertion of the dominance of the American market and the publishers that already serve it well, as authors are likely to place their rights with practitioners in the largest markets. This in turn will lead to the acquisition of many smaller “national” publishers, which cannot compete on a world stage with truly global publishers. But rather than simply becoming sources of editorial product for American-based global marketing machines, smaller publishers operating in different regions will respond through innovation, both in product design (attempting to do electronically what cannot be done in print) and in developing new marketing plans that the giant publishers would be indisposed to pursue.  相似文献
